SHEET-METAL ROOFING.

SPECIFICATION forming part of Letters Patent; No. 374,126, dated November 29. 1887.

Application filed September 10, 1887. Serial No. 249,341. (No model.)

To aZZ whom it may concern.-

Be it known that l, MARIO F. KULP, a citizen of theUnited States, residing at Ohicago, in the county of Cook and State of Illi-' 5 nois, have invented new and useful Improvements in Sheet-Metal Roofing, of which the following is a Specification.

My invention relates to the construction of sheet-metal roofing and caps and the manner of laying the same; and the purpose of the invention is to secure astronger and stiffer standing seam and to provide a roof which embodies less material and which can be laid and removed with less labor and in less time than has heretofore been feasible.

The invention consists in the several novel features of construction and new combinations of parts hereinafter fully set forth, and definitely pointed out in the claims following this specification.

In the accompanying drawings, Figure 1 is a sectional View illustrating my invention. Fig. 2 is a detail view of the cap before application to the seam.

In the said drawings, the referencernumeral 1 designates the roof, upon which the roofingsection 2 are laid in the usual manner, each section having its edges 3 turned upward to abut against the corresponding edge of the adjacent section.

The numeral 4 denotes the cap, which I construct from a strip of metal by bending the same upon itself at or near its longitudinal central line. The marginal portion is then 3 5 bent between the first fold and the edge and is folded down upon the portion 5, which lies between the two folds, and in the edge 6, formed by the last fold, I form perforations 7. The cap is now placed upon the seam, the man ginal portion 8 overlapping it on one side and the portion 5 lying upon the other, and nails, 9, preferably of barbed wire, are driven down through said perforations, passing between the two edges 3 into the roof. The other marginal portion, 10, of the cap 4 is then bent fastenings being comparatively few in numher and readily removable by a straight upward pull, while they afford sufficient strength at the same time to fully resist all strains to which the roofing may be subjected while in use. Expansion and contraction, also, will not affect a roof thus constructed, there being ample space allowed therefor.

What I claim is v 1. In sheet'metal roofing, the combination, with the roofingsections having standing edges, of a cap folded to overlap said edges and having perforations in the line of fold, and nails passing through said perforations and between the standing edges, the remaining portion of the cap being folded to embrace the seam and cover the nails, substantially as described.

2. The combination, with the shcet-metal sections having standing edges 3, of the caps at, having the portions 5 and 8 straddling the said edges, and nails 9, passing through perforations in the cap and between the edges 3 into the wood, the remaining edge, 10, of the cap being bent over the seam and down upon the part 5 to cover the nails, substantially as described.

In testimony whereof I aifix my signature in presence of two witnesses.

MARION r'. KULP.
